RESUMO. Nova espécie de Hylesia Hübner (Lepidopteraa, Saturniidaeniidae, Hemileucinae) do Cerrado brasileiro. O gênero Hylesia Hübner, [1820] compreende cerca de 110 espécies exclusivamente neotropicais, com distribuição do México até a Argentina. Neste trabalho uma nova espécie (Hylesia pseudomoronensis sp. nov..) do Brasil é descrita. O nome específico se refere à similaridade morfológica da espécie descrita com H. moronensis Lemaire, 1976.
